These are only bout 1.5cms at most. So they colour up when adult? They are actually a little pink at the moment. They didn't have any colour in shop

They may have recently arrived at the shop and didn't gain color because of the stress of shipping??? They get to be about 2 cm and the males will get brighter. My females are red too, just not quite as bright. I noticed they really brightened when I started adding baby brine shrimp to their diet.

They were in pet shop for over a month. They had them in a tank in the store room out back. Found they couldn't put them in their normal tanks in shop due to size.
No plants in there tank, and almost over crowded with guppies and platties. I'm guessing the rasboras didn't like that.

They couldn't put them in a normal tank because they are small?

They could have been stressed. They like planted tanks and to be able to hide in and out of my driftwood holes.

I'd give them a special brine shrimp snack and see if they color up in a few days.

Looks more like Boraras merah to me. There seems to be a bit of confusion on the application of common names to species in this genus. Chili/mosquito rasbora seems to be applied to bth B. merah (which is the one you appear to have) and B. brigittae (which is the one Meashkah seems to have). That would account for the difference in the intensity of red coloration. Do an image search on the two species to see what I mean.

Oooooh, I think Tony is right! If they don't color up, I would say that you do have the Boraras Merah species. I know that mine did take a little bit of time to color up, but maybe only a couple of days.
